To constantly retain an ozone water concentration even if the fluctuation of an ozone water consumption arises in a use point, and to suppress the uselessness of water greatly.
An ozone water supply device 1 includes: a high concentration ozone water generation part including an ozone gas generating part 5 and an ozone dissolution module 6; and an ozone water adjusting mechanism 7 which adjusts a given high density ozone water generated in the generation part to the concentration and the volume of water which are needed in each use point UP1, UP2, and UP3. The mechanism 7 includes: drain pipes 27 which drain a portion of high concentration ozone water from each of pipes 20, 21, 22; and injector pipes 13b, 13c, 13d which inject pure water into each of the pipes to dilute high concentration ozone water which remains after draining the portion, wherein the drainage volume of each of drain pipes 27 and the pure water injection volume at each of the injection pipes 13b, 13c, 13d can be adjusted to make ozone water has the ozone water flow volume and ozone concentration depending on the ozone water flow volume and the ozone concentration which each use point use.
